Please give Documentation link for UIExtensions.xml and Registry.xml? I have the schema for UIExtensions.xml and Registry.xml, but I could not find any documentation link on what happens when I click on an item defined in UIExtensions.xml, please help. The schema information links are listed below: http://msdn2.microsoft.com/en-us/library/bb891846(EXCHG.80).aspx http://msdn2.microsoft.com/en-us/library/bb891801.aspx# http://msdn2.microsoft.com/en-us/library/bb891879(EXCHG.80).aspx
